(Etant donné que dans un semaine on sera à nouveau en vacances (cette fois-ci en Suisse avec mon frère et sa famille), je prépare une série de photos sur nos vacances en Toscane "à l'avance" qui seront diffusées progressivement ces prochains jours.)
On est parti de chez nous vers 17h du soir, un vendredi, et sommes arrivés à 2h30 du matin à Montevarchi en Toscane. C'était un peu lent pour 670km, mais avec deux voitures, trois petits enfants et un monstre tempête pour les dernières deux heures, c'était un peu normal.
A part ça, je voulais aussi faire une 'expérience' au niveau de l'économie de carburant. C'était de rouler moins vite pour voir l'influence sur la consommation. Et effectivement, en visant 100km/h, je suis arrivé à une consommation de 4L au 100km, ce qui n'est pas mal pour un break familiale.
Au retour, on a fait plus vite (120km/h en 7h et demi), et la consommation était à 4.5L/100 - ce qui n'est pas mal non plus.
Il y avait d'autres facteurs différentes entre les deux trajets aussi : Au retour j'avais un adulte et beaucoup de litres de vin en plus. C'était de jour, et il faisait chaud alors on avait la climatisation. Puis étant donné que l'Italie est plus bas que la Suisse, on a du monter pour revenir (ce n'est qu'à moitié une blague - de Genova à Aosta, ça monte quasi en permanence).
Je dois avouer que même si j'ai des envies d'écologue, j'adore conduire. Quand j'étais jeune (et célibataire surtout), je m'amusais à rouler le plus vite possible (pas en km/h, mais en heures par trajet - de préférence sur des routes de campagne). Maintenant que j'ai 'des responsabilités', le nouveau jeu c'est de rouler le plus écolo possible (mis à part ne pas rouler du tout, ce qui est infiniment plus écolo).
Ici en Suisse il y a une méthode 'EcoDrive', avec quelques principes de base : accélérer le plus vite possible puis se mettre dans la vitesse le plus haut possible, anticiper la route pour ne pas freiner brutalement, etc.
Pour moi, le secret est d'avoir fait du vélo. Quand on est en vélo, on fait intuitivement en sorte d'épargner nos cuisses. En voiture il faut épargner sa voiture - donc ne pas accélérer à la montée, éviter si possible de freiner. Donner un coup de pédale à la descente pour remonter la pente suivante. Ou alors ne pas pédaler du tout à la descente pour profiter du repos.
Et vous, c'est quoi votre 'système'?
(Given that we will be shortly on holiday (in Switzerland this time, with my brother and family), I'm preparing this series of posts with photos from our holiday in Tuscany. They are 'pre-pared', and will be released gradually over the next fews days)
We left home at around 5 in the afternoon, and got to Montevarchi at 2.30 in the morning. That's a bit slow for 420 miles, but we were a two-car convoy, with three small children, and the last two hours we drove through a wopping rain storm.
I also wanted to 'test' the fuel-economical idea of driving slower to burn less. And I did manage to get 59 mpg by driving at 60mph. Not bad for a family-sized estate (Ford Focus).
Coming back, I went a bit faster - around 75mph - and that got me about 52 mpg, which still isn't bad going.
This wasn't strictly scientific though, as there were other factors involved - coming back I had an extra adult on board - and several litres of wine. And it was day time, in hot weather, so we had the air-conditioning on too. And given that Italy is further down, it was up hill coming all the way back (this is only half joking - from Genova to Aosta it's a gentle slope all the way).
I have to confess that though I have ecological leanings, I also love driving. When I was young (and single), the game was to drive as fast as possible (not in miles per hour, but in hours per trip) - preferably on country roads. Now that I have 'responsabilities', the new game is to drive as ecologically as possible (obviously, not driving at all is the most ecological).
Here in Switzerland, there is the 'EcoDrive' system, with a few tenets: Accelerate to desired speed and change to highest gear as fast as possible, Keep a look ahead on the road to avoid brutal breaking, etc.
My secret is to drive as if I was riding a bike. When you ride, you subconciously do all you can to spare your legs. So you don't try accelerating when you're going up hill. You do all you can to avoid having to break. You give it some extra welly on the downhill if you've got another slope to go up afterwards. Or you coast down hill to give your legs a break.
What's your method?
